Hi,
This is a bit of a long one, though I hope the
answer is short and that someone will be kind enough to help.
I have been getting a bit confused when dealing
with debt interest in investment appraisal and calculating a weighted average
cost of capital.
My issue is as follows:
WACC = Finance and bus. risk same as project
being evaluated
WACC (adjusted) = CAPM Beta factors if only
business/ project risk changes
ADR/APV = Treat business risk as 100% equity
finance and calc PV of financing separately. ADR calculated based on opp cost of
APV at Ke.
Ok this I thought was fairly straight forward,
what is confusing me is that I have seen a few variations in question where
these rules get muddles and it is confusing the heck out of me. In
particular.
Where debt is used to fund a project and asked
to calc a new weighted average cost of capital, assume this is ok as debt is
used to fund an expansion and would effect whole company the same.
A project in a new industry, Beta factors given
in question. Told the project would be funded by2*15% debentures. Solution was
an NPV of project cash flows, with DCF (discount rate) calculated using CAPM.
What is confusing me here is the debt changes the gearing, so how can the
Capm model be used and why is tax relief on debt interest payments
ignored????
A question evaluating a lease buy decision for
an asset. (Nov 08 Exam, BG). The buy option is evaluated as if 100% equity
financé with just tax relief on the capital allowance. The tax relief on the debt
9.2% is ignored. The rate used is post tax marker return on debt (opp cost as lease is alt to debt). Again debt change gearing, but evaluated on opp cost not WACC. Side steps issue, but does not explain ignoring tax relief on debt intrest????
Can anyone clarify what is the missing piece
that makes this clear???
At present I can use the following rule of
thumb, but lack understanding:
* If given a Beta fact use Capm and treat as all
equity financed, ignore relief on debt.
* If evaluating two projects and not asked
specifically to calc APV, treat as all equity finance and ignore tax relief on
debt interest payments.
In summary
Confused regarding tax relief on debt interest
and why when debt is used CAPM and WACC is used when this will effect
gearing.
Please advise
